💅 __bnxt_copy_ctx_mem(9) 💅

ok so bestie, welcome to the Kernel API Manual ✨ — this one lives in section 9 (the kernel-funcs section, you already know 👑) and it's literally all about shuffling host context memory around. Let's get into it 🫶

🌸 NAME 🌸

__bnxt_copy_ctx_mem — copy host context memory 💖

✨ SYNOPSIS ✨

size_t __bnxt_copy_ctx_mem (struct bnxt *bp , struct bnxt_ctx_mem_type
*ctxm , void *buf , size_t offset , size_t head , size_t tail );

like... six whole arguments, no cap 😭 but she's iconic for it

🎀 ARGUMENTS 🎀

  • bp — the driver context 🚗💨 (yes, the big struct bnxt * one, you got this)
  • ctxm — a pointer to the context memory type, fr fr, this is the what kind of context we're talking about 💅
  • buf — the destination buffer ✨ OR pass NULL if you literally just want the length and don't wanna copy anything yet — lowkey such a mood 🙈
  • offset — the buffer offset, aka where in buf the data actually gets plopped down 🎯
  • head — the head offset of the context memory, i.e. where the copying starts from 👑
  • tail — the tail offset (and bestie, that's the last byte + 1, don't forget the + 1 💀) of the context memory, aka where the copy ends 🏁

🦋 DESCRIPTION 🦋

So this function gets called for debugging purposes — the whole vibe is dumping out the host context that the chip is using 🔍🧚

it's giving "peek behind the curtain", it's giving "what is the chip actually doing right now" — and you're the main character holding the flashlight 🔥

⭐ RETURN ⭐

Returns the length of memory copied 📏💜 that's it, that's the whole return. slay.

🌈 SEE ALSO 🌈

ok that's the whole page bestie, go forth and dump some context memory responsibly 🫶✨
